It's easier to set up back yard solar panels than a back yard fuel refinery.

This is such a good point - in every disaster / zombie movie they somehow have gasoline to run cars but no electricity, when in reality it would be the other way round - any existing gasoline would go off after 6 months.

A group of survivors could scavenge a lot of solar panels, bit good luck restarting an oil refinery.

It's an interesting topic, many view gas station and the oil supply as more reliable.. probably a too-big-to-fail aspect of it. But 'if' it crashes, it's indeed a lot harder to compensate for than electricity.

If you have lot of open space with sun exposure, true.

For the average small yard, it's easier to buy a 55gal drum of gasoline and a manual pump if you can anticipate the need.

Growing up in hurricane country, it's something some people did. Buy a drum in the summer and store it. If it wasn't needed, just use it up after November (end of hurricane season).

If someone on planning on doing this, make sure to get 'boat' gas or ethanol free gas. Gas containing ethanol is not made to be stored and separates/attracts water.

You probably have a roof that doesn't have solar panels yet.

It is easier and cheaper to keep 100 litres of gasoline for emergency which would allow to drive at least 1000 KM.

Though probably unwise (and possibly illegal) in many cases.

'backyard' Solar panels won't recharge an EV

acomjean|5 years ago

We have a solar array on the roof. It’s great. But the dc->ac converter needs the grid to be active to do its conversion, so when the power goes out no solar. (I suspect it syncs with the grids 60hz...)

If you include a battery backup in your system, you can run without grid power.

When I worked at a power monitoring start up we had a demo house that was charging an electric rav4, so it’s possible.

I mean, they certainly can. Depends on whose yard I guess.

I charge my EV with solar panels.

nkingsy|5 years ago

With a charger that goes down to 750w you can charge your ev off grid with an inverter.

I currently do it with 12 100w panels. I run ac/dc converters to supplement additional dc from the grid to charge at 1500w, but have a 750w charger for emergencies that will charge directly from the sun with no grid. It does require a small buffer battery to work reliably.

They can, actually. I'm not sure where you're getting your info from, but you can buy home solar panels from Tesla that can easily recharge an EV.
